Description

As reported by ruslan usifov on cassandra-user, he sees exceptions like

java.io.IOException: Невозможно выполнить операцию на сокете, т.к. буфер слишком мал или очередь переполнена
at sun.nio.ch.SocketDispatcher.write0(Native Method)
at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:33)
at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:104)

at sun.nio.ch.FileChannelImpl.transferTo(FileChannelImpl.java:520)
at org.apache.cassandra.net.FileStreamTask.stream(FileStreamTask.java:95)

this appears to translate to "insufficient buffer space."

He also reports that reducing CHUNK_SIZE to 32MB fixes the problem.
